NUT-LOCK.

Specification of Letters Patent.

Patented Aug. '7, 1906.

Application filed February 17,1906. Serial No. 301,608.

of Maryland, have made certain new and useful Improvements in Nut-Locks, of which he following is a specification.

This invention is an improvement in nutlocks; and it consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is-a side view,

partly in section, of a nut-lock embodyingmy invention with the locking-bar in locked osition. Fig. 2 is a side view showing the coking-bar released. Fig. 3 is a detail side view of the bolt. Fig. 4 is a detail perspective view of the nut, and Fig. 5 is an end view of the bolt and nut with the locking-bar in locked position.

The bolt A is threaded atA to receive the nut B and is slotted longitudinally at A from its threaded end or point. The nut B is threaded at B to fit on the bolt and is pro- 1 vided in its oute end with a transverse c annel whose sections O and C communicate at their inner ends with the threaded opening B through the nut, and in the side of the nut B adjacent to the inner end of the channel 0 we form a groove or socket b, in which the hooked end D of the locking-bar D engages,

so the locking-bar and nut will be interlocked when the parts are in the position shown in- Fig. 1. This locking-bar D is pivoted at d at one end to the nut and interlocks-at its other or free end with the nut when in locked position, so the locking-bar cannot jar out of place or be released accidentally or by children or trifiers after it has been once locked. This locking-bar D is made of such width as to fit snugly within the transverse channel in the end of the nut and of such thickness that it.

will when in locked position coincide at its outer edge with the outer end of the nut, as shown in Fig. 1 of the drawings.

When .opened, the locking-bar D will not project beyond the side of the nut B and will afford no obstruction to the application of a wrench in applying or removing the nut.

- To provide for interlocking the bar with the nut, we preferably form the bar D at its outer swinging end with a hook d, the point of which when the bar is forced to locked position by a sharp blow with a hammer orother instrument enters the notch or groove 6 and secures the bar in place, so it cannot be easily released. When desired, the projecting end of the bar may be struck with a hammer, wrench, or other tool and released.

In locked position the bar crosses the slot A and prevents any turning of the nut in either direction.

Having thus described our invention, what we claim as new, and desire to secure by Let ters Patent, is

1. The combination substantiall as herein described, of the bolt, slotted longitudinally from its point end, the nut having .a threaded ,opening to fit said bolt and provided with a transverse groove .or channel across its outer end with its end sections intersecting the threaded opening in the nut and rovided in its outer face adjacent to the inner end of one of the channel-sections with a socket, and a locking-bar pivoted at one end to the nut within the channel at one endof the latter and having its other or free end hooked to engage in the socket in the outer face of the nut, substantially as and for the purposes set forth.

2. A nut having a transverse'channel in' its outer end and a locking-bar operating in such channel and pivoted at one end and extending thence across the bolt-hole in the- .nut and provided at its free end with a hook with a socket, and a lockingbar pivoted at one end and hooked at its other end for interlocking engagement in said socket, substantially as set forth.
